Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual opening mechanism is used, then device complexity is reduced, but ease of operation deteriorates

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical opening with an electronic module that uses a motor to drive a movable member, which releases elastic force to open the drawer. This substitution of mechanical manual operation with an electromechanical system improves ease of operation while managing device complexity through integrated control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If electrically controlled opening is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The electronic module serves multiple functions: it controls the motor-driven movable member, manages elastic force release, and enables wireless operation. By consolidating these functions into a single multi-functional module, the patent improves ease of operation while limiting the increase in overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If synchronization mechanism is added, then productivity is improved, but device complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The synchronization mechanism combines the movement of multiple rails through a shared movable member that releases elastic force simultaneously. By merging the control and movement synchronization into a single mechanism, the patent improves productivity (synchronized drawer opening) while managing the increase in device complexity through integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates automatic and synchronized opening of drawers, enhancing user convenience and reducing manual effort, with potential for power savings through optimized motor operation.

Implementation Method 1

A driving device (204) is configured to drive the movable member (224) to switch to an unlocking state (K2'), so as to release an elastic force (F') of an elastic member (226)

Methodology Applied
Scientific EffectElectromagnetic conversion: Electromagnetic Induction

Implementation Method 2

a movable member (224) in a locking state (K1') arranged on the second rail (228) to lock an elastic member (226), so as to accumulate an elastic force (F') of the elastic member (226)

Methodology Applied
Scientific EffectElastic force: Elasticity

AI summary

A slide rail assembly (22, 202) includes a first rail (30, 230), a second rail (32, 228), an elastic member (68, 226), a movable member (42, 224) and an electronic module (48, 206) . When the second rail (32, 228) is located at a retracted position relative to the first rail (30, 230) and when the movable member (42, 224) is in a locking state, the elastic member (68, 226) is locked to accumulate the elastic force. The electronic module (48, 206) includes a driving device (51, 204) configured to drive the movable member (42, 224) to switch to an unlocking state, in order to release the elastic force of the elastic member (68, 226), such that the second rail (32, 228) is moved from the retracted position along an opening direction relative to the first rail (30, 230) in response to the elastic force of the elastic member (68, 226) .
